<h4><a name = "tag_000_007_538">&nbsp;</a>NAME</h4><blockquote>
mbsinit - determine conversion object status
</blockquote><h4><a name = "tag_000_007_539">&nbsp;</a>SYNOPSIS</h4><blockquote>
<pre><code>

#include &lt;<a href="wchar.h.html">wchar.h</a>&gt;

int mbsinit(const mbstate_t *<i>ps</i>);
</code>
</pre>
</blockquote><h4><a name = "tag_000_007_540">&nbsp;</a>DESCRIPTION</h4><blockquote>
If
<i>ps</i>
is not a null pointer, the
<i>mbsinit()</i>
function determines whether the object pointed to by
<i>ps</i>
describes an initial conversion state.
</blockquote><h4><a name = "tag_000_007_541">&nbsp;</a>RETURN VALUE</h4><blockquote>
The
<i>mbsinit()</i>
function returns non-zero if 
<i>ps</i>
is a null pointer, or if the pointed-to object describes an initial
conversion state; otherwise, it returns zero.
<p>
If an
<b>mbstate_t</b>
object is altered by any of the functions described as "restartable",
and is then used with a different character sequence, or in
the other conversion direction, or with a different LC_CTYPE category
setting than on earlier function calls, the behaviour is undefined.
</blockquote><h4><a name = "tag_000_007_542">&nbsp;</a>ERRORS</h4><blockquote>
No errors are defined.
</blockquote><h4><a name = "tag_000_007_543">&nbsp;</a>EXAMPLES</h4><blockquote>
None.
</blockquote><h4><a name = "tag_000_007_544">&nbsp;</a>APPLICATION USAGE</h4><blockquote>
The
<b>mbstate_t</b>
object is used to describe the current conversion state from a
particular character sequence to a wide-character sequence (or vice
versa) under the rules of a particular setting of the LC_CTYPE
category of the current locale.
<p>
The initial conversion state corresponds, for a conversion in either
direction, to the beginning of a new character sequence in the
initial shift state.  A zero valued
<b>mbstate_t</b>
object is at least one way to describe an initial conversion state.  A
zero valued
<b>mbstate_t</b>
object can be used to initiate conversion involving any character
sequence, in any LC_CTYPE category setting.  
</blockquote><h4><a name = "tag_000_007_545">&nbsp;</a>FUTURE DIRECTIONS</h4><blockquote>
None.
